Be it known thatl, Louis VIcron PIGUET, of theety,.connty, and Stato ofNew York, have invented new and improved'WindingnndSetti-ng-Apparetnsfor Wetches; nd Ido hereby deeinretht the followinig afull, elear,-and exact ,deseription'thereo which will ensihleother-Skilled in the nrt to make ond use the emn'di reference being hadtothe necomponying'drawings, forming 'part of this specification', infwhich- .y

4Similmlotters. of 'reference indieatccorresponding parts." l l Thisinvention reiates to n' new pendant-winder und setter', nud. consists inthe 4lise-of a key; which fits through the pendent, and which has, titsinner end, 'a toothed crown-wheel, which' gen-s inton pinion thatisfitted-in the moi'ment l.' 4. l

The latter .pinion gears into two other toothed 'pinions, -offwhichpneis mounted on a.' swinging bnr end gearsiinto thefbarrelrntcheh i' I'The other is mounted on the oscilleting shiftngbar and can', h y apu'sh-piece, be brought 'tofgenr into the.-

common pinion, whence the settinggupparntus iscompleted.

.A xjepresents the'case or centre".of the-mitch. xB is itspendontfthrough which a pin, is -tted, eo 'as to`rech into the inside ofthe watch. i A I The' outer end of this pin isprovided with n. milledhandle, while o n.ts inner end n. pinion, ,.ie 'formed, which hnstheteeth on'its end, :teflon c crown-wheel, und :is shown in figs. 1 and 2.f l

The ordinary pui1her"for opening the cose onhunting-case watchesbypressure can be nppliedfnfd fitted;`

through-the key C in the ordinary manner.

` The. pinion b meshes into the teeth f a. gear-wheel, D, which' i5fitted in the moilementifof the :iround `u screw,` c, `nnd between'aiever, E, nnd a. cap, 1,1115 chown.

AThe screw4 c is presented ,from turning out `by nnother`screw, e.The-lever E swings or tinnson the pin c', und carries e. pinion, F,which meshes'into Vthe barr.\l-ra.t:.het G, as ehownl l e '-A.'spring,f, presses upon one end ofthe lever or-plate E, so'ns'to throwlthe wheels F and G into gearf'riith each othcm. l i I I I ""7 v l i:

Wh en';the'p inion is turned in the direction ofthe s trrowf 1, in g.1,. the teeth on the wheel, besidestrn ing the wheel `F, havethetendeney to throw the same toward the centre't` tho watch; therebythe pinion F is, se to eey, hemmed in'between the wheels Dnnd G, endtransmits motion from one to the other. i When the wheel D is turned inthe direction opposite to that which is indica-.ted l'bythe arrow 1, theteeth on' D move the wheel F toward the rim of 'thewatch-cas'e, andthereby the pln'te E is turned so as to be forced against Athe springf.Thereby the wheel F is thrown ont of tho wheel G, and thus, when thewheel D is turned in the direetionlast mentioned, it will not wind up,nor willit strain the teeth of the pinion G and thereby tend to breakthe main-Spring, while, when D is turned in the direction ofthe nrrow41, the watch will be wound 'up It will be obserife'd that the teeth onthe'wheels D, F, and G, are not eut,s usual, on cog-wheels, but thatthey are made conical. l

Thiemckes their construction 'easier and'cheper, but they can, ifdesired,- be mede n s usuel.

His the enntion-wheel= 1nd I the hour-wheel, b'oth of which m'e, ofco'rse, toothed. The former meshes into the teeth of n cogwheel orminute-wheel, J, which is of exncty the sume eine and has the semenumber of teeth as the minute-wheel. l

The minute-wheel turns on a'p'in, g, which is' fixed so as that itcannot he moved sidewse. A small pin, t, is formedon tho pin g, andmeshes into the hour-wheel I.

Between the minute-wheel and the wheel D i`s a. pinion, K, which ismounted on a spring-shifter plate, L, that isoperafted by a push-knob,h, from the outside of the watch. 4

By pushing in the knob h the whee'l is broughtageinst the wheels D nndJ, und communication is thas established between the key C and thecannon nnd hour-whhels, and the-hands lcan be set by turning the hey COn the plate L or knob h is formedA n projection, i, ivhioh ts over theend of the plnte E, ond which -when the knob h is pnshed in, tnrns theplate E on its: pin, c, so as to throw the pinions Fand G out of agez.:-Thus, when the setting-apparatus' is in gear, the ninding-apparatnsisout of gear, and vicevvcrsa- The 'teeth of the pinion b being cut on theend, the movementuennbe removed frm or'nsorted in the case nithouttrouble n ey 'as on ordinary movement, and the p inion'b nelevdvnot beinade of every exact size, asrlong asit is large enough to reach thelevel'of the wheoll),h l I EThe necesity of making and adjusting thecase with lthat greet accuracy-'and precision, which is' necessary anordinary pendant-winders, is thus overcome. 'Y I By the arrangement ofthe enlarged cannon-pinion und hou'r-wheel, the hands nr'e steaded, undmo'rc power,

well es security of motion, is provided. I
